- iPhone Duo at $1,999: the case for it—and the case for waiting

A missing Bluetooth control, an undiscoverable headset, and silent connected earbuds are different problems. Here is how to choose the next useful action.
- Five minutes before a meeting, Windows cannot find your AirPods
No button on the back does not mean a defective case. Pairing differs by AirPods generation, and a successful connection is only part of getting meeting audio ready.

- Your iPhone mirrors to the TV, but the video is black. Is Wi-Fi really the problem?
A missing receiver and a black video inside a working mirrored screen are different failures. Find where AirPlay stops before replacing network hardware.
- Your USB-C cable charges the laptop. Why is the monitor still black?
Power arriving is not proof that video can travel. Trace the laptop, cable, and display before spending money on a replacement that may solve the wrong problem.
